The global regenerative thermal oxidizer market size is expected at USD 10.84 billion in 2024 and is projected to grow at a CAGR of 4.5 % to reach USD 13.51 billion in 2029.
A regenerative thermal oxidizer is a type of combustion device that reduces the amount of volatile organic compounds, hazardous air pollutants, and odors in the air by first converting the emissions into CO2 and H2O using heat before releasing them into the atmosphere.
Inlet switch valves direct the pollutant-filled air into one of the energy recovery canisters after a high-pressure supply fan propels exhaust fumes into the Regenerative Thermal Oxidizer. The first heat exchanger container is where heat is transferred from the ceramic medium to the air as it continues to ascend from the valve assembly. Next, the preheated air enters the combustion chamber and is maintained at a high temperature, nearly oxidation-ready. While in the combustion chamber, the contaminant is eliminated. Next, the clean, hot air exits the combustion chamber and passes through a second energy recovery chamber where ceramic material recovers the heat produced during thermal oxidation. Finally, the outlet switch valves and the exhaust stack send the cooled, clean air into the atmosphere.
Enough amounts of chemicals, hydrocarbons, and organic molecules are released into the atmosphere during the industrial process. As a result, a significant amount of carbon dioxide is responsible for the greenhouse effect in the air. To combat these dangerous gases released by various industries, governments are now putting strict regulations in place. These are the main factors fueling the market for regenerative thermal oxidizers. These regenerative thermal oxidizers are in high demand due to the massive industrialization that is taking place in most developing nations today. This has led to a great demand for these products. As a result of the various advantages that these oxidizers offer, such as high VOC destruction rates, low operating costs, and high thermal efficiency, there has been a tremendous increase in the growth of this market.
The demand for primary products is increasing globally, motivating developing countries to increase their production capacities and leading toward industrialization. However, industrialization has resulted in environmental damage due to industrial pollution. So that negative effects on the environment are minimized, adequate and effective pollution control methods are needed. Highly polluting sectors include thermal power plants, coal mines, cement, sponge iron, steel & ferroalloys, petroleum, and chemicals, which produce dust, smoke, fumes, and hazardous gas emissions.
The high cost of the regenerative thermal oxidizer and the maintenance cost, as it contains many working parts, restrict the market's growth. Several companies globally are launching different air cleaning equipment on the market, giving tough competition. In addition, several Governments are changing the safety measures, so the company needs to regularly improve its features to remain in the competition after some time.

In 2021, the product type segmentation was led by the Rotary Regenerative Thermal Oxidizer, and throughout the forecast period, it is anticipated to increase at the fastest rate. The HC treatment effectiveness of the Rotary Regenerative Thermal Oxidizer is 99% or higher. In addition, 95% of the heat recovery volume is recovered. The system can treat gases at 50 to 1000 Nm3/min. Stable, high treatment effectiveness, high heat recovery rate, and available at a reasonable price are only a few of the features.
Compact Type Regenerative Thermal Oxidizer is also growing at a significant rate due to various features such as being used In Heavy duty construction, incorporating two separate poppet valves in a 2-canister, single vessel design for cleaning air compliance, compact design, ease of installation, and availability with a hot-side bypass system for high solvent load applications all contribute to excellent performance.
The Double Bed Regenerative Thermal Oxidizer was leading the control type segmentation in 2021. It is expected to grow at the highest rate compared to the other types during the forecast period. The various benefits of a double-bed over the others, such as a system with a reduced initial investment cost and one that is smaller and simpler to install in terms of size, are preferred to having a two-bed regenerative thermal oxidizer system with excellent thermal efficiency and minimizing capital costs. These benefits are responsible for driving the growth of the regenerative thermal oxidizer market. Numerous industries prefer double beds over other types as they can install more equipment in the area.
The chemical sector in the end-use industry is leading the market share in 2021 and is projected to grow at a high rate during the forecast period. Chemicals are transformed during the production and processing of organic raw materials, intermediate goods, and even specific chemicals. However, technical procedures result in the production of highly odorous fumes and exhaust that contain some harmful, corrosive compounds. These hazardous gases can affect the health of workers. As a result, regenerative thermal oxidizers are used in chemical plants to remove hazardous gases at very high temperatures from the air.
Pharmaceutical companies are in second place in terms of market share. Before the medication is packaged in a batch, it must be heated, broken down, reformed, sealed, and cooled. When multiple processes occur, such as alcohol, heating, and cooling equipment, a significant number of VOC emissions are produced. An RTO can reduce batch manufacturing emissions while reducing them to a minimum. Furthermore, a regenerative thermal oxidizer can reduce fumes and gases so that the fumes would need to reach exorbitant levels to catch fire and/or produce an explosion. Using volatile chemical compounds can result in explosions or fires, posing a risk to employees.
In the regional segment, Europe holds the largest share of the global market in 2021 and is projected to grow during the forecast period. The presence of numerous manufacturing industries in the region, such as chemicals, automobiles, pharmaceuticals, semiconductors, and others, is the driving factor for the demand for regenerative thermal oxidizers. In addition, according to the European Green Deal, the EU updated the Ambient Air Quality Directive to align air quality standards more closely with the World Health Organization's guidelines (WHO). As a result, the manufacturers have started installing the oxidizers to not go against the government's laws.
North America and Asia-Pacific are in second and third place in the regional segment, respectively. The strict government rules in North America to combat the air quality challenges drive growth. As a result, huge investments are made in research and development, and strict rules for industries to follow to purify hazardous gases. Furthermore, in Asia-Pacific, there is a rapid increase in industrialization and investments in adopting regenerative thermal oxidizers.

In June 2022, Catalytic Products International announced that the installation of a new regenerative thermal oxidizer (RTO) at a two-piece, polymer-coated steel can manufacturer in the Midwest had been completed, which will help to reduce the amount of volatile organic compounds (VOCs) produced during the metal decorating process. Due to the facility's ongoing expansion with new steel can processing and metal decorating lines, this new RTO is a replica of an existing RTO established in 2017. With continuous + 98% destruction rate efficiency (DRE) and + 95% thermal heat recovery, the 7,500 SCFM RTO eliminates incoming VOCs. In August 2020, Anguil Environmental Systems announced the establishment of a wholly-owned subsidiary as part of its development of operations in India. They have a direct presence now that they have an office in Gujarat. The company will provide a full range of water treatment and air pollution control technologies for manufacturing activities because they already have established partners and several successful installations across India.
In March 2022, Durr AG announced that it would install seven regenerative thermal oxidizers (RTO) air pollution control systems for Yisheng Petoxidizersal Co., Ltd., a chemical company. Durr provided Yisheng Petrochemical with seven identical turnkey Oxi for the regenerative thermal oxidation process. X RE systems and an equal number of Sorpt.X SW wet scrubbers. Each system consists of a clean gas stack, a downstream scrubber, and nine Oxi. X RE towers. With 2.31 million Nm3/h of treatment capacity among the seven units, a nine-tower RTO has a treatment capacity of roughly 330.000 Nm3/h, making it one of the largest RTO installations in the world.
